Product Description


Serious Buyers and Transparent Operations
Tantalite Ta2o5 30% - 50% Concentrate
U th 0.3% or less
LOI and NCND to Commence

Our current price for 30% - 50% Ta2o5 is $ USD per Pound. This price includes commissions and to begin negotiations we need a Letter of Intent (LOI) and NCND. With this Letter of Intent (LOI) we can begin to move forward with all the legal documents. We will check your refferences of prior sales. Once you send an LOI the following will begin....

Example Ta2o5 Formula Per MT

2200 * Ta2o5% = X lbs.

X lbs. * $/lb. = $/MT


2200 * 30% = 660 lbs.

660 lbs. * $130 = $85,800 per MT


2200 * 40% = 880 lbs.

880 lbs. * $130 = $114,400 per MT

≈ Price per pound varies depending on current market price.

1. The Buyer intends to purchase Tantalum Ore from the Seller at a price agreeable between the parties. The price will be based on the percentage of Ta2o5 found in each ton of ore. The product will be paid in U.S. Dollars unless otherwise agreed to in writing.

2. The Buyer further intends to purchase ores containing approximately X metric tons of tantalum pentoxide equivalent per month from the Seller at the same price agreed to above for a period of one year so long as the average spot price does not go down.

3. The ore is expected to contain at least equivalent to 30% by weight of tantalum pentoxide (whether in the form of metal or pentoxide) ThO2 U3O8 less than 0.25% by weight, and the radioactivity of the ores below 0.3 uSv/hr as measured on the surface of the drum (or surface of the container)

4. The total purchase price will be based on the amount of tantalum pentoxide (Ta2O5) based on the tested percentage of Tantalum (Ta205) contained in said ore.

5. Tantalum pentoxide content will be based on assay survey conducted by independent parties, which are well recognized and have global operations, such as A.H. Knight, S.G.S., and Alex Stewart. The survey is to include:

a. Sampling,

b. Net and gross weights of each drum,

c. Sealing of each drum, and

d. Analysis for moisture, Ta2O5, Nb2O5, U3O8, and ThO2 contents

Costs of the survey will be paid for by the Seller on the first shipment and by the Buyer on future shipments.

6. When contract with the herein agreed terms is signed and sealed the Buyer oe it’s assigns agrees to tenure a SBLC for 100% of the anticipated approximate agreed selling price.

7. Once the assay report is completed to buyer’s satisfaction, the Buyer is to pay full invoice amount by wire transfer to bank of Seller’s choice on presentation of the Bill of Lading. The freight and insurance required for shipping from exit port in Brazil will be the responsibility of said Buyer.

8. Original copy of following document must be presented for payment:

a. Signed original invoice

b. Original Bill of Lading

c. Packing list by the independent 3rd party

d. Assay report by the independent 3rd party

e. Certificate of container seal the independent 3rd party

f. Certificate of mine

g. Brazil export license

9. The parties further agree that the purchase price will be based on FOB exit port Brazil.

10. This contract shall run for (1) one year or (12) twelve consecutive months from first shipping date.

Thank You and we look forward to receiving your LOI,

Tantalum Applications

Tantalum usage has developed significantly over recent years and is now used extensively in the manufacture of capacitors in electronic applications such as mobile phones and computers; in superalloys with nickel and cobalt for the aerospace industry; in specialty metal products for the medical, pharmaceutical, and chemical industries; and in metal carbide for the metal working tools industry.

Superior Dielectric Properties
Possessing the capability to grow uniform and stable oxides with good dielectric properties.

Used extensively in the manufacture of tantalum capacitors with higher capacitance voltage, better heat transfer and frequency characteristics than other types of capacitor.

Constituting the major significant application of tantalum.

Excellent Corrosion Resistance
Immune to corrosive attack by acids and liquid metals.

Widely applied in the chemical, Medical and pharmaceutical industries; fabrication of heating elements, surgical implants, combustion turbines and jet engines.

Good Thermal Conductivity
Used as an efficient heat transfer surface, especially in acidic or corrosive environments.

High melting Point: 2,997 oC
High temperature strength, combined with workability and corrosion resistance.

Used in the fabrication of superior heat shields; heating elements; electrodes and other high temperature components.

Ductility, Workability and Weldability
Tough, durable and ductile, surpassing most other refractory metals.

Coltan/Tantalum is used primarily for the production of tantalum capacitors, used in many electronic devices.
